Who the BCLALUMG-SKG Clarinet in A Is For

The Backun BCLALUMG-SKG Lumiere is a professional custom A clarinet designed for players who want a traditional French-style instrument feel with modern Backun engineering and precise, stable intonation. It is well suited to orchestral and chamber musicians, advanced conservatory students, and doubling professionals who need clarity and focus from the highest altissimo through the low register.

What distinguishes the Lumiere within Backun’s lineup is the complete redesign from the bell up and its use of the Backun Scale bore paired with a complex taper, plus sculpted tone holes that support an even, fluid response. The inline trill key architecture is designed to improve function while helping keep complex tone hole work out of the waterline, and the black leather pads and updated touch pieces are aimed at players who prioritize tactile control, seal consistency, and refined key feel.
